Update VMware Tools from PowerCLI

For vSphere installations, the VMware Tools drivers allow virtual machines to connect to the ESX or ESXi hypervisor for optimal performance, as well as take advantage of all of the current virtual devices. Each incremental update of VMware ESXi or ESX may incur an update for the VMware Tools installation for the guest virtual machines. Keeping VMware Tools up to date can be a task that gets away from you quickly.
